海外TECH	DEV Community	Scott's Journey on Passing AWS DevOps Engineer Professional Certification	https://dev.to/fantastichsieh/scott-s-journey-on-passing-aws-devops-engineer-professional-certification-2h79	Scott x s Journey on Passing AWS DevOps Engineer Professional Certification Content TablePrologueOfficial Exame Guide Tips for Real ExamComputeNetworking amp Content Delivery Developer ToolsStorageLogHigh Availability Fault Tolerance and Disaster RecoverOthersImplementation SuggestionsConclusionReferences PrologueAfter passing the AWS DAS in February this year I d been fascinating about how to become a professional lazybones in spare time apart from building custom CDK constructs sharing at the AWS Taiwan UG internal sharing in my own company and recording for an external session All of sudden I felt gotta keep moving on towards goals after studying the quintessence of lazybones for a while So the journey of pursuing the AWS DevOps Engineer Professional Certification began at that moment Official Exame GuideLike you will check how many mountain trails you gotta walk through for taking down the Taipai Grand Trail and what materials you need to collect so that you could get a legendary weapon Kudzu for your ranger in Guild War To get the One Piece of the DOP you have to evaulaute whether you ve had quite some sense what specific enterprise scenarios cases are going to show up in this certification and what AWS services you could consider resolving the issues transpired in those cases From the website you could see Validation on candidates ability Implement and manage continuous delivery systems and methodologies on AWSImplement and automate security controls governance processes and compliance validationDefine and deploy monitoring metrics and logging systems on AWSImplement systems that are highly available scalable and self healing on the AWS platformDesign manage and maintain tools to automate operational processesRecommended knowledge and experience Experience developing code in at least one high level programming language building highly automated infrastructures and administering operating systemsUnderstanding of modern development and operations processes and methodologiesAbility to implement and manage continuous delivery systems and methodologies on AWSAbility to implement and automate security controls governance processes and compliance validationAbility to define and deploy monitoring metrics and logging systems on AWSIn the exam guide we could see the content expounds more detail into fields that this certification is going to test whether you can respond rapidly towards forementioned enterprise scenarios and understand what AWS services can fulfil the requirements in those cases Domain SDLC Automation Domain Configuration Management and Infrastructure as Code Domain Monitoring and Logging

right services based on business needs e g RTO RPO cost Determine how to design and automate disaster recovery strategiesEvaluate a deployment for points of failure Tips for Real Exam ComputeSuch as EC Elastic Beanstalk Lambda ECS and Fargate you need to grasp basic understanding of these services By saying basic understanding it doesn t mean reading over related official documentations is enough but at least you gotta equipped with operation experience of those services via the Web Console Of course if you work hard enough deploying the services by CloudFormation CFN will be used in the rest of the article or the CDK can be beneficial both to smashing DOP and your own DevOps experience EC can be utilized to become an AP or API server From scratch you probably will grow your system gradually from a single functionality based on requirements During the time you might still log in the EC where your system or function aggregation resides via ssh with a key pair to manage the code snippets that support your system or service Aside from ssh is there a safer way to log in Have you ever operated EC Instance Connect and Session Manager in AWS Systems Manager To log in an EC server via two forementioned methods do you know what steps you need to go through on authorization and configuration so that a user can log in via the services As time passes you might realize that during some specific time spans requesting number to your service or server is large and your server cannot handle this copious amount of requesting Do you know in this moment you could consider using Elastic Load Balancing and EC AUto Scaling to tackle this kind of issue About launch templates LT and launch configuration LC can you explain the difference between the two and what scenarios they are suitable Is there any connection between Auto Scaling Groups ASG and LT and LC What are EC Auto Scaling lifecycle hooks What states are included in the lifecycle hooks What events or states are followed after the scale out and scale in events If traffic in the coming future cannot be predicted or depicted among multiple scaling strategies of Auto Scaling what option you can consider After grasping all of the scaling strategies what are their proper usage scenarios What phenomena will make auto scaling start to work Can I trigger auto scaling based on some condition What conditions can I select If auto scaling is at the scale in state before compute instances are going to be terminated you want to snapshot the instances or create the AMIs do you know in what state of the lifecycle hooks allows you to define the forementioned custom actions Or what if there are running compute instances in an ASG and for regulation purpose the instances need to be attached the nd network interface for connecting to an independent subnet managed by other business unit what you can do in the lifecycle hooks in order to achieve the requirements Introducing Native Support for Predictive Scaling with Amazon EC Auto Scaling In terms of Elastic Load Balancing can you name all of the load balancers In what aspects there is the difference between Application Load Balancer ALB and Network Load Balancer NLB In the OSI model which kind of OSI level for load balancing do they support respectively If load balancing is required to be integrated with Lambda what load balancer should be chose Do you know what things Elastic Beanstalk as a service can do for you automatically What are Elastic Beanstalk composed of Can environment be categorized If there are multiple kinds of environments what specific tasks they are especially good at What is ebextensions for What can it achieve Can I modify hardware spec of compute instances via ebextensions Model serving in Java with AWS Elastic Beanstalk made easy with Deep Java Library With micro service architecture becoming more popular and popular after assimilating related concepts its history and what AWS services can assist you in building micro services you ll enter the world of Lambda ECS and Fargate How many phases are there in terms of AWS Lambda execution environment What programming languages does it support natively or directly If a programming language that isn t supported by AWS is preferred to be executed what method you could consider to achieve the goal What are the least permissions for an AWS Lambda function to be executed If integration with other AWS services via Lambda is required what needs to be done as wishes If a web server hosted on an EC instance with authentication functionality is intended to be migrated to Lambda as serverless service what components might be changed compared to the original architecture How to get notified on specific Lambda function error patterns using CloudWatch ECS is for containers as a managed service what components are there in ECS Like task definition auto scaling container agent etc you re supposed to distinguish components of ECS Just follow classic examples on the official documentations for hands on experience with explanation in the technical documentations and a fabulous late melt with Hokkaido milk What is the relationship between ECS and ECR Do they need each other to work or they can be combined to work together Is there any one between the services that can execute other task independently Figure in How Steamhaus Used AWS Well Architected to Improve Sperry Rail s Artificial Intelligence SystemYou still need to manage web servers by deploying your applications or services to ECS there exists operation cost to some extent Hence AWS who captured the customers need launched AWS Fargate What differences there are between the ECS container service and AWS Fargate Why the need of AWS Fargate is getting more and more When you attempt to figure out carefully you ll realize what elegant and efficient developing experience is Figure in Game Server Hosting on AWS Fargate Networking amp Content DeliveryOn the aspect of VPC you ll also need some understanding after all the services mentioned so far are built upon VPC except Amazon ECS Anywhere Amazon EKS Anywhere and AWS Outposts Like what public subnets private subnets route tables network ACL and security group SG are What are ENI CIDR Internet Gateway NAT Gateway and VPC endpoints etc When grasping ENI at the beginning level you could schedule some time to go deeply about what is the difference among ENI ENA and EFA About Route you re suggested to have sense on how many kinds of DNS records there are such as A AAAA CNAME Alias records etc You gotta at least read through the documentation of routing policies Geolocation and geo proximity are all connected to geolocation What is their difference What can be achieved via DNS failover What options can be considered for DNS failover Developer ToolsDeployment ModelsNow we are about to enter into the scope of deployment models If you look carefully at Point of the SDLC Automation in domain knowledge of the exam guide you ll see blue green canary and red black deployment models Regarding the blue green deployment I personally thought the speech given by Andy Mui and Vlad Vlasceanu will be a good start Its content delivered concise and informative information on what possible combinations there are to run through the blue green deployment on the aspect of EC and ECS Aside from some super helpful comparison strategies at data level were also suggested such as when a blue gree deployment is about to be progressed if data schema is also going to be changed what corresponding methods can be implemented The red back deployment and blue green deployment can be regarded as the same deployment model You could spend some time figuring out their mindset in back and then focus on the blue green deployment After all in a presentation file titled Deployment Strategies on Kubernetes in the CNCF also equals the blue green deployment and red black deployment On the aspect of computing you could see AWS offers numerous selections How to progress the blue green deployment for EC How about the blue green deployment via CFN for ECS How to execute a canary deployment for pure Lambda If there is a serverless service combined with Lambda and Amazon API Gateway a newer version to be deployed is required while visiting the original API should be allowed what needs to be configured in procedure Blue Green Deployments with Amazon Elastic Container Service AWS CloudFormation and AWS Serverless Applicaiton ModelYou must manipulate CFN by sorely viewing technical documentation you might not be able to have quite solid grasp In CFN how do you refer to resources in nested stacks When infrastructure becomes huge is there any organizing practice that can be followed in terms of stack building What are cfn init cfn signal cfn get metadata and cfn hup for What resources support the UpdatePolicy attribute With AWS AutoScaling AutoScalingGroup what other more specific options are provided for managing ASG via CFN Do you know that custom resources can invoke Lambda functions and AWS APIs For example making Lambda functions managed by CFN updatable which are stored in a S bucket where versioning is open configuring event notification to Lambda on an existing S bucket right now CDK already supports this scenario creating and updating AWS well architected reviews making the ARN of a Lambda function deployed by AWS Serverless Application visible to the following S Object Lambda deployment etc WaitCondition in CFN can make signals without accessing the Internet Best practices for organizing larger serverless applications AWS CodeCommit AWS CodeBuild AWS CodeDeploy and AWS CodePipelineDevelopers might agree with that git is a popular tool for version control and CodeCommit is a managed service of version control by AWS To empower developers in a team to execute specific git commands towards a CodeCommit repository what needs to be set related to permissions If a Git repository is going to be migrated to CodeCommit what steps are necessary If an action in CodePipeline failed what can be implemented to notify DevOps engineers or related developers Not through AWS Chatbot In a CodePipeline pipeline combined with CodeBuild and CodeDeploy if the insertion of code testing function test unit test integration test bra bra is intended what you can do to achieve the goal In a CICD pipeline what way is feasible to make applications conform to security regulations How many kinds of events can be listened in CodePipeline What servcies are used for listening CodeDeploy can not only assist in deployment for AWS resources but also IDC machines If we want to deploy to IDC machines via CodeDeploy what are the prerequisites How do you build a cross account CD pipeline If sensitive information will be accessed in a CICD pipeline do you know that AWS Systems Manager Parameter Store and AWS Secrets Manager can be adopted pertaining to security concerns Figure in CI CD on Amazon EKS using AWS CodeCommit AWS CodePipeline AWS CodeBuild and FluxCD StorageHow many storage classes are there in S What are the differences among these classes In what circumstances you should select Intelligent Tiering And in what situation One Zone IA will be more suitable What configuration you need to deal with so that the storage level of objects will be deleted and transitioned according to some time unit What is ACL How many kinds of pre defined S ACLs are there What is the bucket policy of an S bucket for What is the application possibility on S object tags Amazon RDS and AWS DynamoDB as the solutions for RDBS and NoSQL respectively what criteria you might consider when it comes to selecting storage place for your data NoSQL doesn t mean that there is no relation among data also it is not an invention to replace RDBS About this topic I suggest you could refer to the one hour speech given by Rick Houlihan as AWS NoSQL Principal Technologist you ll have a wonderful trip there What is the functionality of Amazon Aurora Global Database What are Amazon DynamoDB Global Tables for Either Auora or DynamoDB how to do the Multi AZ and Multi region backups What are GSI and LSI Regarding RDS for improving read or write throughput you probably will consider utilizing Amazon ElastiCache either Memcached or Redis To achieve the same result do you know there is a thing called DAX If you still have time go check RCU and WCU If data in DynamoDB is intended to archive to S based on some time frequency what services can be integrated to achieve this Figure in Use Amazon DynamoDB Accelerator DAX from AWS Lambda to increase performance while reducing costs LogWhat is the major difference between CloudTrail and CloudWatch To reach real time processing on CloudWatch logs what you can do Is there any difference between CloudWatch Events and EventBridge For example if you want to monitor cross account launch failure on EC instances what you should do To record topic timestamp resource IP in SES to a log group in CloudWatch what service can be adopted to achieve the goal If analyzing log data is intended is there any functionality in CloudWatch that can help me query Is there any choice on storage location for logs Figure in BBVA Architecture for Large Scale Macie Implementation High Availability Fault Tolerance and Disaster RecoverWith proper understanding on compute networking and storage services you ll start to digest the concepts of high availability failover and disaster recovery DR About this field I recommend Reliability Pillar in the AWS Well Architected series It is a book which organizes the concepts pretty much well At least you need to know how many levels are defined in terms of disaster recovery What is the definitions of RTO and RPO In the real world the people you re discussing with might not understand what the backup amp restore is or what the pilot light is Yet by talking with time unit you still can roughly get what level the disaster recovery being discussed belongs to About exam questions related to this field DR you will be in hell if you don t have solid grasp of the forementioned AWS services You not only learn these services functionalities you gotta compare responding time on the aspects of backup and relaunch also By going through this way you ll be able to resonate in the content in Reliability Pillar Take a brief example There is a company which has infrastructure in three continents The base is Europe and Asia and the United States are extended areas There are analysts in the three continents They analyze log data via a web application The data is stored in DynamoDB of Europe and ECS on Fargate with ALB and auto scaling serves their web application Now the analyst in Asia and the United States are complaining about slow response time and the speed of specific analysis is starting killing them How can you modify the infrastructure architecture and then send the anaysts a sincere Bon Jovi have a nice day smile Figure in Implementing Multi Region Disaster Recovery Using Event Driven Architecture OthersI suggest you also need some understanding on Amazon ES and AWS Storage Gateway i e what are their functionalities How the architectures look like You have to grasp thoses to some extent AWS OpsWorks can be used to manage instance configuration What two automation services is it based on What is the difference among AWS OpsWorks Stacks AWS OpsWorks for Chef Automate and AWS OpsWorks for Puppet Enterprise AWS OpsWorks and AWS Systems Automation can both be taken to execute automation tasks What is the difference Amazon Inspector can be helpful on security What is its difference to Amazon GuardDuty Except vulnerability assessment on AWS resources according to assessment rules is there anything else that AWS Inspector can do What does AWS Trusted Advisor do What is its difference to AWS Config Apart from that AWS Config rules can work in a single account if the enablement of AWS Config rules across multiple accounts is required what needs to be done If specific actions are intended to be executed automatically after targets are discovered by AWS Config rules what can be adopted to reach this kind of automation What is Tag Editor for What we can do via AWS RAM Improve monitoring of AWS Systems Manager Agent How to visualize multi account Amazon Inspector findings with Amazon Elasticsearch Service Implementation SuggestionsIf possible please get hands on experience on all the AWS services mentioned above at least via the Web Console Either they are simple examples some of them I won t say it s easy I prefer to take the term of classic to describe organized by the documentations of AWS services or films on Youtube that were published by passionate developers all of them are options that you can run through Like ECS a beginner example or an auto scaling example both can be found on the Internet Furthermore if time permits attempt to craft some application examples via CFN or CDK From the AWS official documentations to AWS Samples to AWS blogs they all provide CFN templates that you could deploy quickly Just make your hands dirty with description on the technical documentations the ride can reach the final for sure Lastly if you still can squeeze somte time by accident go manipulate CDK to build some applications based on miscellaneous scenarios with any one of the services mentioned above Following the suggestions I believe on the road of pursuing DOP you ll feel safe As of me looking to the past I had experience on the CICD in the IDC and the CICDs with pure AWS solutions I implemented the latter one with CFN and CDK I also once built the construct of CICD combining AWS Glue DataBrew About the compute services once built them via CFN and CDK also A project where the front end and back end are split A project with pure back end A project for CloudFront extensions For example like DNS record type that points to an ALB the application and renewal of ACM certifications etc When reading new articles in the AWS blogs I ll try as much as possible to manipulate their mindset via CFN if there exist and then ponder possible variation based on them It s not that as easy as you might feel when reading through this article yet it s very similar to leveling up in an online game From lvl to lvl you just need exactly that much It s inescapable ConclusionIn the DOP exam it s included numerous condensed real scenarios brief and comprehensive to test whether you can act properly by given limitations or conditions and tackle the issues Via grasping the essence of the AWS services and figuring out the solutions built by other developers you ll be eventually capable of resolving problems swiftly when facing various and diverse of them About the DOP exam normally latest features won t come to you In computing such as Lambda container Amazon ECS Anywhere Amazon EKS Anywhere Instance Refresh of EC Auto Scaling In networking like Amazon Route Resolver DNS Firewall Or like CFN modules and CFN registry DOP usually tests your horizontal level and some will be deep detail about the ks knowledge you might consider the CKA CKAD and CKS created by the CNCF Concerning the SDLC automation its implementation might differ because of industries enterprise culture and so on What DOP tests you mostly focuses on horizontal level and the AWS services Like unit test integration test and static analysis you won t see in this exam Regarding their detail readers can consider joining the DevOps Taiwan group on Facebook In addition to annual party merely watching conversations among DevOps experts may already give you lessons learned Of course not only the forementioned tests will be discussed trust me you have a bumper harvest by participating In the end wanna share I took the exam on the Pearson VUE platform There will be a proctor who watches you during the exam shy shy gt lt The available languages are English and Japanese I chose the English exam and an English proctor strongly suggest you should bring your personal laptop Actually in the guidance of the online exam it is also suggested that it s better to bring your own laptop I didn t capture the information and took the company laptop to welcome the exam And what happened is the anti virus software in the company laptop didn t give the green light to the VUE online program for exams It took me around one hour to negotiate with the proctor to wait for my colleague the unit who manages the anti virus software coming to take a look but to no avail the proctor cancelled the exam and rushed back to my living place to take my personal laptop The most impressive thing is I purchased the exam at AM and chose one which starts at AM Different proctor in the first exam and second exam I spent around hours going through questions and checked those which were tagged by me previously in the rest of time In the last minutes nothing I could do anymore and submitted my exam Eventually I got the ONE PIECE of DOP If anyone who is thinking about taking the exam intends to choose the online way PLEASE use your personal laptop Trust me you ll thank me If you prefer testing centers you probably need to evaluate the COVID pandemic situation By this channel you also lose the flexibility of going through the exam minutes later right after purchasing However you might benefit from the availability of physical little white board If you d learned something on taking the DOP exam from this sharing this article would fulfill its mission Good luck fellows Day is stasis Followed by irrelevance Followed by excruciating painful decline Followed by death And
